Application Research Of Wireless Anti-theft System Based On GSM/GPRS

With the improvement of people’s living standard and the enhancement of securityawareness, people begin to care about their own life and working environment, not only thesurrounding environment comfort and humanity, but also higher requirements is put forwardon the living and working environment safety and intelligent, security system has become partof essential to life.This paper is discussed from the security system of the background, researchsignificance, research status and development trends, focusing on the GSM/GPRS wirelessanti-theft system in the application of the hardware design, software design and systemdebugging. The hardware design include system design, various sensors circuit design(infrared sensor, temperature sensor, smoke sensor, gas sensor and so on), wirelesstransceiver circuit design, small system of MCU STC12C5A60S2design and GSM/GPRSmodule SIM300. Software design include Chinese short message compiler code, C languageprogram design, compiled and download. system debugging include machine debugging,serial debugging,software debugging, SMS and the overall circuit debugging. The downloadof the MCU and other related components are soldered to the PCB board, power up, thewhole system can be through a variety of sensors on the measured area of the real-timemonitoring and the abnormal condition via the wireless transceiver module is transmitted tothe MCU, after analysed and processing, finally through the AT instruction by the SIM300module for mobile phone users to send alarm information and the sound and light alarm.Looking forward to the future, along with the3G mobile communication system to thecommercial,3G technology will promote security monitoring and mobile communication thedepth of integration, mobile phone monitoring, remote video monitoring, various detector flexible matching, it will provide the best solution for the theft alarm, fire, gas leakage,emergency events and so on.
